To all whom it mag concern:

Be it known that I, JULIUS SEDLACEK, a subject of the Emperor of Austria-Hungary, residing at Nuremberg, in the Kingdom of Bavaria, Empire of Germany, have invented a new and useful Improvement in Condensing- Water and Air Cooling Apparatusfor Refrigerating-Machines, (for which I have obtained Letters Patent as follows: in Germany, No. 72,657, of January 13, 1893; in England, No. 9,530, of May 14, 1895; in France, No. 226,556, of December 21,1892; in Switzerland,No.7,363, of July 22, 1893, and No. 8,798, of June25, 1894; in Italy, No. 1,194, of March 28,1893; in Belgium, No. 85,843, of August. 25,1894; in Austria-Hungary, No. 1,089/5,637, of May 6, 1893, and No. 10,239/l9,809, of August 30,

1893,) of which the following is a specification.

The object of my invention isto provide an improved construction of apparatus for cooling (and incidentally purifying) air, and to that end utilizing otherwise waste cold radi ating from the refrigerator, and for cooling the condenser-water.

Referring to the accompanying drawings, Figure 1 shows my improved apparatus, by a view inelevation, as connected with a room to be cooled, shown in sectional elevation. Fig. 2 is a view in sectional elevation of the condenser-water cooler; Fig. 3, a'similarview of the air cooler and purifier,the section-being taken at the line 3 on Fig. 4'and viewed in the direction indicated by an arrow and Fig. 4, a section taken at the line 4 on Fig.

3. and viewed in the direction indicated by an arrow.

A is the air-cooler, comprising a metallic shell M, which should be incased in awoode'n shell K, with a dead-air space between the two, and centrally within the shell M is' the refrigerator proper, formed with the coiled pipes r, incased in a metallic shell 19, for containing the brine or other liquid medium to be rendered cold by the expansion into gas in the pipe-coils of the liquid carbonic acid or ammonia employed for refrigeration.

The space between the outer and inner shells M and pis divided into a vertical series of circumferential chambers 0, formed with sheetmetal rings a, supported at suitable intervals apart, said chambers intercommu'nicating from one to the other through openings 5, affording a circuitous passage through them. .The brine or other liquid is circulated contin'uously through the chambers 0 and inner shell p by the action of a suitable force-pump V, which forces it upward through the interior of the shell 10 to the upper end thereof, where it flows over suitably-supported perforated troughs c, whence it falls circuitously through the chambers o, accumulating in the lowermost chamber, from which it is withdrawn by the action of the pump to be again forced through the inner shell. In traversing itsupward course from the pump the liquid is rendered cold by contact with the refrigerator R, and in falling through the chambers 0 it is subjected to the further influence of cold radiating from the shell 10. Screens d are shown to be interposed in chambers 0, for a purpose hereinafter described.

Air is forced by means of a blower D into the lowermost chambero to rise against the downflow through the chambers of the cooling liquid, which renders the air cold, being supplemented by the cold radiating from the outer surface of the shell p. The screens (1 in the chambers 0 tend to divide the air and coils S and being congealed thereon-in the I form of frost. The pipe at leads to a storagechamber B and introduces therein for its refrigerating effect the purified, cooled," and dried air.

For the purpose of cooling the water used for condensing the gas after the latter has been utilized by its expansion for its refrigerating effect and compressed and which is commonly allowed to run off a condenser similar in construction to the cooler already described is employed. The condenser O, the details of which are illustrated in Fig. 2, comprises a set of coils r, surrounded by a metallic shell p, these beinginclosed in an outer metallic shell M, between which and the shell 19 are provided chambers 0, formed, like the chambers 0, of sheet-metal rings a, the chambers intercommunicating through a circuitous passage afforded by suitably-placed openings (not shown, owing to the nature of the view selected for illustration in Fig. 2, but like those in the air-cooler) and having interposed in them the screens d. A forcepump V produces a continuous circulation of the liquid up through the shell p, from the top of which it flows over suitably-supported perforated troughs c and down through the chambers 0' to the lowermost thereof, whence it is again forced upward by the action of the pump. For cooling the condenser liquid I utilize the surplus and otherwise waste cold of the air employed for its refrigerating efiect in the chamber B, leading therefrom the air through a pipe at into the condenser 0 near its base, and from the upper endof which there leads a pipe 01 into the base portion of the cooler A, the lastnamed pipe containing the blower D for the entire system of pipes 01, n, and 7?, which connect the cooler A, the condenser O, and the room B to direct the air from the latter into the condenser, from the condenser into the cooler A, and thence back into the room. The liquid in falling from the perforated troughs 0 through the chamber 0' is encountered by the uprising cold air from the pipe at, which air imparts its cold to the liquid, thereby adapting the latter to cool and condense the refrigerant in the coils 0, which may communicate with the coils in the cooler A in an ordinary manner through the pumping apparatus commonly employed in ice and refrigerating machines.

The air employed for cooling the liquid in the condenser 0 might be taken from the surrounding atmosphere, though it is preferable to employ that used in the room B, whereby the desired continuous air circulation is attained through the apparatus.

YVhat I claim as new, and desire to secure by Letters Patent, is

a 1. In a refrigerating apparatus, an aircooler comprising, in combination, a refrigerator R having the surrounding shell 19 incased in a shell M, a vertical series of intercommunicating chambers 0 between said shells, means for forcing air upward through said chambers, a pump for forcing the liquid upward through said' refrigerator to fall through said chambers, and thereby produce a continuous circulation of the liquid, and an outlet for the air, substantially as described.

2. In a refrigerating apparatus, an aircooler comprising, in combination, a refrigerator R having the surrounding shell 19 incased in a shell M, a vertical series of intercommunicating chambers 0 between said shells, coiled pipe S in the upper part of the cooler in the path to the air-outlet at therefrom and afiording a drier, means for forcing air upward through said chambers to said outlet, and a pump for forcing the liquid upward through said refrigerator to fall through said chambers and thereby produce a continuous circulation of the liquid, 1 substantially as described.

3. In arefrigerating apparatus, a condenser 0 comprising, in combination, the coiled pipe 1' incased in a shell 19 surrounded by a shell M, a vertical series of intercommunicating chambers 0 between said shells, means for forcing air upward through said chambers, and a pump for forcing the liquid upward through said shell 19 to fall through said chambers and thereby produce a continuous circulation of the liquid, substantially as described.

4. In a refrigerating apparatus, the combination of an air-cooler A having an outlet n and containing the refrigerator R and the intercommunicating chambers 0 surrounding said refrigerator, means for forcing air upward through said chambers, a pump for forcing the liquid upward through said refrigerator to fall through said chambers and thereby produce a continuous circulation of the liquid, and a condenser 0 having an outlet 92 in its upper end communicating with said coolernear its base, said condenser containing the incased coiled pipe r and the circumferential intercommunicating chambers o and communicating from its base portion with the outlet '11, of said cooler, and a pump for forcing the liquid upward through the incasement of said coiled pipeto fall through said chambers and thereby produce a continuous circulation of the liquid, substantially as described.

5. In a refrigerating apparatus, the combination of an air-cooler A, a condenser 0 communicating from its upper end with the cooler at its base, a blower D in said communication, a chamber B communicating with said cooler at its upper end and with said condenser at its base, and pumping means for circulating the liquid of the air-cooler and condenser through each, substantially as described.
